S_AXI_LITE's assigned address is out of range #6

As shown the CTRL0 address was assigned to 0x04_0000_0000. However, the S_AXI_LITE address channel is 32-bit, which is incompatible with assigned address.

fpgadeveloper commented 4 years ago

A 32-bit AXI-lite interface can be assigned a 40-bit address as we have done in this design. If you find any documentation to the contrary, please post a link here. If you have a warning message from the Vivado tool, please post it here.

That's a stupid question. Never mind.
